Answer: [tex]18\sqrt{2}\\\\[/tex]
This is the same as saying 18*sqrt(2) or you could say 18√2
============================================================
Explanation:
We'll be using this square root rule: [tex]\sqrt{A}*\sqrt{B} = \sqrt{A*B}[/tex]
So we could have this as our steps:
[tex]3\sqrt{12}*\sqrt{6}\\\\3\sqrt{12*6} \ \text{ ... Apply the rule mentioned}\\\\3\sqrt{72}\\\\3\sqrt{36*2}\\\\3\sqrt{36}*\sqrt{2} \ \text{ ... Apply the rule again, but in reverse}\\\\3*6*\sqrt{2}\\\\18\sqrt{2}\\\\[/tex]
Therefore, [tex]3\sqrt{12}*\sqrt{6} = 18\sqrt{2}[/tex]
The basic idea is to first combine the roots using that rule. From there, we factor the radicand such that we pull out the largest perfect square factor. This will allow us to break the root apart and fully simplify it.

What is the product 1.3(-3.1)(4.2)
The value of product will be;
⇒ 16.926
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is,
⇒ 1.3 (- 3.1) (4.2)
Now,
Since, The expression is,
⇒ 1.3 (- 3.1) (4.2)
After product, we get;
⇒ 1.3 × (- 3.1) × (4.2)
⇒ 4.03 × 4.2
⇒ 16.926
Thus, The value is = 16.926

Kim and Tom both cycle to work from their
homes, at the same speed. Kim lives 20 km
away from work, and Tom lives only 15 km
away from work. It takes Kim 1 hour more to
cycle to work than Tom. Determine how long
Tom takes to get to work.
Answer:
3 hours
Step-by-step explanation:
You find the LCM between 20 and 15, which is 5. This means that Kim and Tom are both biking at 5 miles per hour, meaning that to determine how much time Tom takes, you would do 15/5, which is 3 hours.
Time taken by Tom to get office is 3 hour
Given information:
Distance of office from Kim house = 20 km
Distance of office from Tom house = 15 km
Kim take 1 hour more
Find;
Time taken by Tom to get office
Computation:
Assume;
Time taken by Tom = a hour
So,
Time taken by Kim = (a + 1) hour
[tex]Speed = \frac{Distance}{Time}[/tex]
So,
[tex]\frac{20}{(a + 1)}=\frac{15}{a} \\\\20a = 15a + 15\\\\20a - 15a = 15\\\\5a = 15\\\\a = 3[/tex]
So,
Time taken by Tom = 3 hour

Step-by-step explanation:
[tex]\sin(\theta + \phi) = 2\cos(\theta - \phi)[/tex]
Using the addition identity formulas, we can write
[tex]\sin{\theta}\cos{\phi} + \cos{\theta}\sin{\phi} = 2\cos{\theta}\cos{\phi} + 2\sin{\theta}\sin{\phi}[/tex]
Dividing both sides by [tex]\cos{\phi}[/tex], we get
[tex]\sin{\theta} + \cos{\theta}\tan{\phi} = 2\cos{\theta} + 2\sin{\theta}\tan{\phi}[/tex]
Dividing both sides by [tex]\sin{\theta}[/tex], we get
[tex]\tan{\theta} + \tan{\phi} = 2 + 2\tan{\theta}\tan{\phi}[/tex]
or
[tex]\tan{\theta}(1 - 2\tan{\phi}) = 2 - \tan{\phi}[/tex]
Rearranging the terms,
[tex]\tan{\theta} = \dfrac{2 - \tan{\phi}}{1 - 2\tan{\phi}}[/tex]

Use the converse of the Pythagorean Theorem to check whether a triangle whose sides are of lengths 11, 60, and 61 is a right triangle.
First square the lengths of the sides.
11^2 =
60^2 =
61^2 =
Answer:
yes a right triangle
Step-by-step explanation:
Using the converse of Pythagoras' theorem.
If the square on the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 61 and 61² = 3721 , then
60² + 11² = 3600 + 121 = 3721
Since 61² = 60² + 11² then the triangle is right.

Jeanne makes jewelry and has an idea for a new pair of earrings. She wants to make a sketch of her design, but only has a marker, a pencil, two pieces of paper, and a coffee mug. Use these items to construct the shape of the earring Jeanne is envisioning.
Step 1: Jeanne traced her coffee mug on her piece of paper. How might she use paper-folding to find the center of the circle? (2 points)
Step 2: Show how a second circle should be drawn in order to continue the construction. What can you say about the radii? Explain your work. (4 points)
Step 3: Describe the final steps in constructing the shape of the earring. Include a drawing.(2 points)
To complete her design Jeane will need to draw a smaller circle within the circle, and by using this circle and previous lines she can create the diamond design.
What should Jeane do after tracing the first circle?The second step is to fold the paper vertically and horizontally to determine the lines that divide it by half.
What is the third step?The third step is to draw a smaller circle within the first circle and make sure the circles are aligned in the center. This circle will have a smaller radius than the first one.
What is the final step?By using the previous lines Jeane should draw the desired design as shown in the image.

If your teacher is referring to four digit numbers with those tiles, where the tiles cant repeat, then we have 2 choices for the last slot (the units digit). Those two choices are: 6,8.

Select the correct answer. Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of g(x) if g(x) = f(x) - 3? A.It is the graph of f(x) translated 3 units down. B.It is the graph of f(x) translated 3 units to the left. C.It is the graph of f(x) where the slope is decreased by 3. D. It is the graph of f(x) translated 3 units up.
Answer: Choice A) translated 3 units down
Explanation:
x is the input while y = f(x) is the output. If we say f(x) - 3, then it's the same as saying y - 3. This means g(x) = f(x) - 3 subtracts 3 from each y coordinate of the points on f(x). This visually moves the entire f(x) curve down 3 units

You go to the grocery store to buy milk and some eggs. Milk costs $3.67 and eggs cost $2.40. You want to make sure you have enough money. Estimate the cost of these two items to the nearest ones place.
Answer:
Step-by-step explanation:
Let's start by round 3.67. We look at the key digit which is 6 in this case. Since 6 is greater than 5, 3.67 will round up to 4.
The key digit in 2.40 is 4. 4 is not greater than 5, so we round down to 2.
2+4=6
Therefore, an estimate of these two items to the nearest ones place is $6.
Answer:
$2 for the eggs and $4 for the milk
Step-by-step explanation:
Since the eggs cost $2.40 and after the 2 you can see that there is a 4, " 5 or more we add one more, 4 or less just ignore", so it stays $2. However the milk costs $3.67, and here you can see that after the 3 there is a 4, so since it's more than 5 we change the estimated amount to $4.

What is the equation of the line that passes through the point (-5,-7)(−5,−7) and has a slope of \frac{2}{5} 5 2 ?
Answer:
y-y1=slope (x-x1)
where x1=-5, y1=-7 and the slope=2÷5

y-(-7)=2÷5{x-(-5)}
y+7=2÷5(x+5)
y+7=(2x+10)÷5 cross multiply

Devon is 2 times Sydney's age and sum of their ages =75
Answer:
Devon is 50 and Sydney is 25
Step-by-step explanation:
We know that d + s = 75 and that Devon is two times Sydney's age. This can be represented by 2s + s = 75 (keep in mind that 2s = d). Simplify the equation.
3s = 75
s = 25
Now we can substitute this in the original equation.
d + 25 = 75
d = 50
Best of Luck~
Answer: Sydney=25 Devon=50
Step-by-step explanation:
Sydney's age is represented by x and since Devon is 2 times older (his/her) age would be represented as 2x. So added together would be 3x. So 3x=75. 75/3=25. So x=25 meaning that Sydney is 25 and Devons age is 50 as 25x2=50.

brenda bought 8 cupcakes at $1.59 each and 5 pies at $5.99 each . how much more did he spend on pie's than cupcakes
Answer:
17.23
Step-by-step explanation:
Find the cost of the cupcakes
8* 1.59= 12.72
Find the cost of the pies
5*5.99 =29.95
Subtract the cost of the cupcakes from the pies
29.95-12.72=17.23
Answer:
Money spent more on pies than cupcakes = $17.23
Step-by-step explanation:
1 cupcake = $ 1.59
8 cupcakes = 8 * $ 1.59
8 cupcakes = $12.72
1 pie = $5.99
5 pies = 5 * $5.99
5 pies = $29.95
Money spent more on pies than cupcakes = Pies - Cupcakes
Money spent more on pies than cupcakes = $29.95 - $12.72
Money spent more on pies than cupcakes = $17.23

Here are 2 points in the plane.
Using only a straightedge,can you find points in the plane that are the same distance from points A and B. Explain your reasoning
9514 1404 393
Answer:
no
Step-by-step explanation:
Using only a straightedge, you cannot measure distance, so cannot ensure that any two distances are the same.
__
The points of interest are on the perpendicular bisector of AB, which can be constructed using a compass and straightedge. The straightedge alone is insufficient.
